Sleipnir 6: An Unusual New Web Browser for Windows and Mac

Sleipnir, most Norse historians will tell you, was an eight-legged horse existing only in myth. Thanks to the work of Fenrir Inc. (a name also steeped in Norse myth), this is no longer the case due to their Sleipnir web browser. While the browser has been around for a long time, the latest versions take a very different approach to browsing the Web when compared to the competition – and in fact to their predecessors.

Like most web browsers, it offers familiar import functionality, allowing you to bring bookmarks from Firefox or another browser over and continue to access them. This is where the easy comparisons stop; as you can see, Sleipnir has a radically different UI to any other browser you’ve likely ever used.

While we are using the portable version in these screenshots, the standard version does use English as the default instead of Japanese; this is likely an oversight given that the developers are based in Japan. Sleipnir 6 shares its rendering engine, Blink, with Google Chrome and Opera, so unsurprisingly it handles web pages quickly in spite of the surprising UI.

Using Blink means that there are quite a few elements of Sleipnir that feel immediately familiar. None are more obvious than the settings screen, though the automatic translation of pages in foreign languages is almost identical to within Chrome. In some ways, Sleipnir does feel like a heavily modified version of Chrome, but there is no element more radically different than the tabs. Tabs are displayed as thumbnails along the top of the window, rather than as strings of text. It is an unusual way to deal with tabs, and in our experience was not particularly quick at producing thumbnail images. These thumbnails could be a real pain to deal with on low resolutions, though they are unobtrusive when viewed at 1920×1080.

One of the main selling points of Sleipnir is that it handles fonts extremely well, as seen above. Firefox is shown on the left and Sleipnir on the right; the fonts are notably thicker and more rounded, and this is particularly clear with the bold type. The Fenrir website mentions font rendering several times with a focus on emulating the design of OS X instead of Microsoft’s own ClearType rendering method. Whether this looks better or not is highly subjective: while many people do prefer the font rendering of OS X, many also find Windows easier to read. Still, with the demise of Safari for Windows, Sleipnir marks the first re-entry into bringing OS X style fonts to a Windows web browser.

Sleipnir goes further than Safari ever did, though. Passwords and other information can be backed up to the cloud via Fenrir Pass, which does more than just store passwords. Based on the functionality located under the ‘share’ button, Fenrir Pass also supports storage of articles for later reading, similarly to the ‘Stash’ function added to the latest versions of Opera and Instapaper. Sending articles to mobile appears an interesting function as well, though could be seen by some as bloat.

For all the radical UI changes and new features Sleipnir offers, it does feel familiar at least. The browser seems to meld UI elements from numerous other web browsers, past and present, to create something totally unique. For instance, the ‘Sleipnir’ button in the upper left is functionally identical to the ‘Firefox’ button added to Mozilla’s browser in version 4.0, while the tab thumbnails are similar to functionality in older builds of Opera. By taking these older elements, Sleipnir is able to be surprisingly intuitive for a browser that seems so daunting at first.

Do you need it though? For many users, the UI could be rather jarring, given that it is so different from the designs that have been established as normal over the past few years. That said, we personally like the browser’s emulation of the font rendering on OS X and consider it pleasant for reading extended articles. While it is possible to get this in other browsers, it requires more work and thus, Sleipnir may be of interest, even if only for accessing and reading content online. Should you choose to use the browser for more than this, then it is also a positive that it supports Chrome extensions.

Are you tired of using Windows or OS X as your operating system and thinking of trying out, and possibly switching, to Linux? In this Complete Beginner's Guide to Ubuntu 16.04 ebook, we will guide you and show you everything you need to know about Ubuntu - the most popular Linux distro.

When it comes to browsers I think a new browser has to bring what others have and bring it better. In addition to this the new browser has to bring features that no other browser has. Of course, it has to be secure and low on resources, with speed. The problem with a new browser is that many main web sites don’t recognize and won’t work with a new browser. When it comes to Microsoft it wants you to use I.E. latest version. I have tried other browsers, since Firefox, I.E, and Google Chrome, and certain web sites just wouldn’t work or load, and recommended I use a different browser. My main stay browser is Chrome and then Comodo Dragon. I.E. when I have too.
